What is Leibniz formula for π?

Leibniz formula for π is a special way to calculate the number π, which tells us how big around a circle is compared to its width.

Imagine you have a pie, your favorite kind! Now, imagine cutting that pie into very thin slices and then adding up some of those slices in a pattern. That's kind of what Leibniz did with numbers instead of pie.

Leibniz used this simple pattern:

1 - 1/3 + 1/5 - 1/7 + 1/9 - ...

Each term is like a slice of pie, sometimes you add it, sometimes you subtract it. If you keep going with this pattern forever, the numbers will slowly get closer and closer to π, which is about 3.14.

It's like taking turns adding and removing tiny pieces from your pie until you get just the right size. The more slices (or terms) you use, the better your guess for π gets!

So even though it looks simple, this formula shows how math can be both fun and powerful, like having a recipe that helps you make perfect pies every time!
